Question

can anyone help me in this determination of integrating factors..ill give medal

Answer 1

y(2x-9y)dx+2x(x-3y)dy=0

Answer 2

@abb0t

Answer 3

i got IF= \[e ^{x^2}\]

Answer 4

how can i find the general solution for this? \[2x^2e ^{x^2}ydx-xe ^{x^2}y^2dx+ye ^{x^2}dx+xe ^{x^2}dy-ye ^{x^2}dy=0\]

Answer 5

you have
P(x,y) dx + Q(x,y) dy = 0
so do
\[ \int_0^x P(x,y) \ dx + \int_0^y Q(x,y) \ dy \]

Answer 6

ops

Answer 7

this must the process

Answer 8

yes, that is what you do
if we use M and N instead of P and Q
the first step is to do
\[\int M \ dx \]
